The nine-member South Korean troupe Twice’s has returned with a new album, TWICEcoaster: LANE 2, and they released the video for the group’s electro-pop bop, “Knock Knock.”

Following the girl group’s debut in 2015 with The Story Begins, Twice have quickly become one of K-pop’s hottest new exports, hitting Top 10 with their “Like Ooh-Ahh,” and notching the No. 1 spot with both “Cheer Up” and the insanely infectious “TT.” Their last mini-album, Twicecoaster: Lane 1, was released in October of 2016.
